Hollow ZnS and ZnO architectures are fabricated by employing Z[n.sub.5][C[O.sub.3]][sub.2][OH][sub.6] microspheres as the sacrificial template. A possible formation process from Z[n.sub.5][C[O.sub.3]][sub.2][OH][sub.6] microspheres to core/shell structured ZnO/ZnS composites was proposed by arresting a series of intermediate morphologies.

Nanowires and nanoplates are grown on an oxidized Si substrate at relatively low temperatures of 250 and 300 degree Celsius, respectively starting from a mixture of Zn and BiI3. Analysis of photoluminescence spectra suggested that the nanoplates contain more oxygen vacancies and have higher surface-to-volume ratios than the nanowires.
